COMBINED WEED-CUTTER, CULTIVATOR, AND PULVERIZER. 7

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed March 31,1903- Serial No. 150,418.

To (all whom it may concern:

' invented a new and Improved CombinedWeed- Cutter, Cultivator, and Pulverizer, of which the following is a specification.

My invention relates to cultivators, and particularly to that class adapted to the cultivation of listed corn.

The object of my invention is to provide a new and improved cultivator for cutting the weeds on the sidesof the furrow and for destroying the weeds and pulverizing the soil on the ridges and hilling the corn with any desired amount of clean. soil; to provide a machine whichcan be easily guided in the furrow and which has rotary disks and cuttingblades capable of efiicient adjustment in the various positions desiredthat is, the disks and cutting-blades maybe adjusted to any required angle, also to any required depth, regardless of the position of the runners-and also means whereby each set of disks may be adjusted laterally and independently ofthe other set.

My invention consists in various constructions and combinationsof the same, as will be hereinafter described, and pointed out in the claims.

Reference will be made to the accompanying drawings, which form a part of this specification, and in which similar characters of reference indicate the corresponding parts of the different figures.

Figure 1 is a top plan view of the cultivator. Fig. 2 is a median longitudinal vertical sectionof the same, showing one-half of the sled, with the arrangement of disks, levers, cuttingblades, &c., with a part of the sled cut away to show the connecting-rods u and c. Fig. 3

is a detail view of the casting or leg .by means of which the end of the disk-carrying shaft or rod nearest or toward the sled runners is held in proper position with reference to the adjustable pipe to which the upper part of the l casting is attached. Fig. 4 is a detail view showing the bearings, boxings, and means of lowering the disks and also thesliding bearings upon the cross arch-bars, by means of which the rock shaft or rod upon which the adjustable pipes slide is held firmly to the cross arch-bars of the cultivator-frame. Fig. 6 is a median vertical sectional View of the bearings and boxings at the outside end of the disk-carrying shaft, taken on a line parallel to the sled-runners.

The letters A A indicate the light metal framework of the sled-runners, consisting of upper frame-bars as well as lower runners. The runners are firmly held by the cross archbars B B and the arch e. The runners are to be from eight to fourteen inches apart, as may be desired, in order to straddle the row of corn growing in the furrow or trench in which listed corn is planted. The arch e and the crossarch-bars B B are to be high enough to pass over young corn without injury thereto.

At the top the .cross arch-bars are curved backward in an arc with a radiusequal to the length of the I'Odll in order that the upper part of the rock-shaft M may be guided between these arcs by means of guide-lugs 5 5, which extend outward at the upper bend in the rockshaft M, and thereby hold the disks firmly in position at all times when the disks are raised or lowered.

The cross arch-bars B B are attached to both the upper frame-bars and the runners A A by means of bolts, as shown in Fig. 2. The guiding-feet are attached to the arch e' and to the frame of the runners A. The lower ends of the guiding-feet are turned or bent backward in line with the runners, which runners are bent upward in front and follow a short space behind these feet. In the space between the runners and the feet are the cutting-blades E E. These blades are adjustably attached to thebars m by means of bolts and the slots 11,. Said bar m is also adjustable by The rock shaft or rod M, which passes between the cross arch-bars BB in the sliding works inside of the cross arch-barsB B upon guide-lugs 5 5, as shown in Fig. 5. These lugs extend outward at the upper bend in the rock shaft or red M between the cross arch-bars B B, and thus the backward curve in the cross arch-bars B B rocks the rock shaft or rod M in such a way as always to keep the sets of disks at the same distance from the bars to which they are firmly held by the rods to u when the disks are raised or lowered by means of the lever D raising or lowering the rock shaft or rod M.

Standards P P are attached at their lower ends to both the upper and lower frame-bars of the runners A and A and then extending upward they are bent backward in their upper part and attached to the arch crossbar B.

q is a rock-shaft journaled in bearings Z Z on the standards P P. One end of this shaft has an angular rearwardly-extending arm q outside of the bearing, which is slotted at its rear end at D. Secured to the shaft 9, outside of the other bearing Z, is a lever D, which has a pawl 1", adapted to engage the segment R, secured to the standard P. The lever D has a rearwardly-extending arm parallel to the arm q of the shaft q and also slotted at its rear end. The slots of D and g engage the lugs projecting from the outside of the vertically-sliding bearings s s, and by means of the rock-shaft, lever, and rack the bearings can be adjusted vertically.

The pipe K is slipped over the end of the rock shaft or red M and secured preferably by means of the set-screws 7 7 in such a manner as to be adjustable upon the rock shaft or rod M. The ends of the rock shaft or red M may be made either round or square, as may be desired. The leg W is rigidly secured to the end of the pipe K which is nearest or toward the runners by means of the U-shaped bolts 8 8. The lower end of the leg W is forked, having in the forks slots z' 7; running transversely, so as to allow the bearings around the shaft 2, and thereby the inner end of the shaft 10, to be drawn forward and let back. The outward end of the pipe K is bent downward at right angles, as at K. To the lower end are attached castings X X by means of the bolts 6 9. Within said castings X X are other castings Y Y, which inclose the boxings of the disk-carrying shaft 19. Said castings Y Y are secured to each other by means of small bolts, as shown in Fig. 4. One of these castings Y fits into a groove in the casting X. Said groove runs transversely and allows casting Y room to slide horizontally. The other of these castings'Y fits into a groove in casting X, which also runs transversely. This said casting Y is also pivotally attached within casting X by means of the vertical bolt 10, which passes through these castings at the place where castingY fits into the groove in casting X and so adjusted as to allow casting Y to swing freely horizontally upon said pivot in casting X.

The bars j j are attached by any suitable means to the upper and forward portion of the frame of each of the runners, respectively. Then extending outward and back they are bentin such a manner as to pass through plate 2 and extend horizontally at right angles to the sled-runners. The bars a. a. are attached toward the rear onto the upper portion of the frame-bars of each of the runners and then extend outward and forward in such a manner as to pass directly beneath plate 2 at the bends in the bars y'j and furnish a base for the attachment of plate 2, which has a segment-rack upon it, and pivotally attached to said plate 2 is the lever 1. Said lever 1 has pivotally attached to it the draw-rod v. Said draw-rod o is attached at its rear end by any suitable means to the bearings on the disk-carrying shaft, thereby making it possible to adjust the disks to any angle desired by throwing the lever 1 forward and backward. The rod u is pivotally attached at its forward end to the bar 1' by means of the casting Z5", which is made adjustable upon said bar 7' by means of a setscrew. Said rod a is also pivotally attached at its rear end to the U-shaped head of the bolt 6.

The bars jy'are braced by the rods H H extending from the bars y'j to the lugs 3 3 on the outward ends of the bars (1/ a, being secured thereto by means of nuts.

As the sled is drawn forward by means of the draw-rods g the knives E E cut the weeds along the sides of the furrow. The depth to which it is desirable to cut the soil upon the ridges is regulated by forcing the disk gangs into or out of the ground by means of the lever D, and by this means the disk gangs can also be regulated to the depth of the furrow in which the cornislisted. The thoroughness with which the soil is to be turned is regulated by the levers 1 1 being drawn forward or let back and thereby giving the disk gangs more or less slant. The distance of the disk gangs from the corn, and thereby the amount of soil thrown around the corn, is regulated by adjusting the disk gangs in toward or outward from the sled upon the rock-shaft M.

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent, is

1. In a combined weed-cutter,cultivator and pulverizer the combination of parallel runners with sufiicient space for the plants to pass between them when the sled is drawn forward; two parallel cross arch-bars, said cross archbars being curved backward in an arcin their upper portion; a rock shaft, or rod, which works upon sliding bearings between these cross arch-bars, said rock-shaft being bent upward just inside of these cross arch-bars in the form of an arch with guide-lugs extending outward at the upper bends in said arch 7 justable pipe upon said rock-shaft; the means of securing said pipe in adjusted position upon said rock-shaft; the means for raising or lowering said rock-shaft upon the cross arch-bars; and also the means for keeping the sets of disks always at the same distance from the point from which they are drawn, comprising draw-rods pivotally connected with the bearings at the outer ends ofthe disk-gangs and extending forward and pivotallyconnected with the cultivator-frame; and

draw-rods pivotally connected with and extending forward from the bearings at the inner ends of the disk gangs and pivotally connected with levers upon the cultivator-frame, all substantially as shown and described.

3. In a combined weed-cutter, cultivator and pulverizer the combination of two parallel runners suitably connected; two sets of laterally, perpendicularly and angularly adjustable rotating disks; the bars extending horizontally outward from said runners on each side of the sled, one of said bars extending outward and forward and the other outward and backward; the means of attaching the sets of disks to said bars; also means whereby the angular position of the disks may be controlled; and the cutting-blades,and the means of adjusting said blades to the depth and slant required all substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscriblng witnesses.
